Road Crank
|
100% Pure Crank from Paul Componenet Engineering. Our Road Cranks take advantage of the narrower chainstays found on road frames, and the narrow chain line of our High Flange hubs. These cranks use a specially designed interlocking chain ring/crank interface. Four 7075 Aluminum chain ring bolts with T25 Torx heads bolt through the chain ring and into the reinforced spider on the crank arm. We've made the threads even deeper and reinforced the spider making the assembly impossible to strip. We machine the crank arms from 2024 aluminum, a very strong and stiff material. They are given a high polish finish and optional black anodization. We currently make the Road Crank in two lengths: 165mm and 170mm. The chain rings are machined out of 6.3mm thick aluminum plate; very sturdy. They're currently designed only to work with ⅛" chains (track and bmx), and are unpolished. Chain rings come in two patterns, determined by their size. 46 and 48 tooth rings have our "Royal Flush" suit of cards design while smaller rings get a "four circles" treatment. Now for the important part. There are two square taper designs in use today, JIS (Shimano, and pretty much everyone else except Campagnolo), and ISO which is used by Campagnolo. We designed our cranks around Campagnolo 111mm width spindles, so that's what you should use. They make a really affordable one called the ACH, and they make some really nice expensive ones too. We also strongly recommend the Phil Wood 110.5 Campy taper bottom backet which lets you fine tune the chain line. Check out this online review of the Road Crank by Fixed Gear Gallery. Tech Info:
